Effects of fluoride on in vitro hydroxyapatite demineralisation analysed by 19F MAS-NMR
IntroductionFluoride plays a major role in inhibiting enamel dissolution and promoting fluorapatite formation. Porous hydroxyapatite (HAP) discs can be used as an enamel analogue in artificial demineralisation/remineralisation studies.MethodThe aim of ...

Native Cd+ in sedimentary fluorapatite
A native Cd+ centre (5s1, S = 1/2) was detected in natural sedimentary fluorapatite using Electron Paramagnetic Resonance (EPR). The Cd+ centre generated by artificial X-ray irradiation of the same sample has an EPR spectrum similar to the native Cd+ centre but differs in its thermal stability. The artificial Cd+ centre exhibits fast thermal decay, i.e.

An NMR Study of Biomimetic Fluorapatite – Gelatine Mesocrystals [PDF]
AbstractThe mesocrystal system fluoroapatite—gelatine grown by double-diffusion is characterized by hierarchical composite structure on a mesoscale. In the present work we apply solid state NMR to characterize its structure on the molecular level and provide a link between the structural organisation on the mesoscale and atomistic computer simulations.

Physicochemical and Antibacterial Characterization of a Novel Fluorapatite Coating [PDF]
Peri-implantitis remains the major impediment to the long-term use of dental implants. With increasing concern over the growth in antibiotic resistance, there is considerable interest in the preparation of antimicrobial dental implant coatings that also induce osseointegration. One such potential coating material is fluorapatite (FA).
